Scientists create self-cloning lizards

Genetics researchers have created a new species of lizard by mating two other distinct species.
The new lizards are all female and can reproduce without needing to be fertilized, effectively cloning themselves. The creatures are doing so well in fact that scientists are thinking of giving them a name as a new distinct species.
A genetics research group working in a lab in Kansas, has succeeded in creating a new species of lizard by mating two distinct species of North American Whiptails, both native to New Mexico.

Really not that exciting. From the article. "Geneticists have been trying for years to create a new breed of pretty much anything by urging lab “volunteers” of differing species to mate with one another, not exactly earth shaking science when you consider a dog that tries to mate with a human leg.""

Recall the "Star Trek" episode - "Day of the Triffids." We're there, they need to make a self cloning Hawk to eat them! Like the African Bees, somehow these will get out.

Trouble with Tribbles? I think that's what you mean. . . No, these animals aren't like that. You don't put them in a room with a bunch of food and suddenly get thousands of them. Self cloning doesn't mean multiplying like a bacteria, it just means genetic diversity gets shot to the floor. Honestly, the only good thing about this would be the ability to survive if all the males of the species died off. I believe I heard that Komodo Dragons actually could use Parthenogenesis, which is the official term for all-female reproduction. The cool thing, it somehow produces male offspring without having...

Right so Lizards will multiply to inffinity? I was wondering do Americans even think before doing something....Playing with nature? Well playing with a gun more likely, which can backfire... Are you aware that genetics isn't confined to America??

if it is the same creature that always clone themselves, dosen't that mean that this race of lizard will evantualy face a genetic breakdown? Whitout a genetic partner to provide new DNA to mix and thus create a viable offspring who is stronger do to the genetic mix of the parent and thus maybe give a new gene to future generation, well the DNA code would get weaker and weaker by time? I don't know if you are all following what i am meaning. That a sexual partner help by giving offsprings new DNA if some new born got a new DNA sequence that would help futur offsprings survive when it'll get in ... [More]

It really makes you worry when they keep creating all these new species, sheep, an array of insects, lizards...ya.... I believe this technology from geneticist is nothing new and some humans probably 'cloned' themselves centuries upon centuries ago, and the technology is just being rediscovered it will only be a matter of 20 yrs or even quicker in which the first human or 'female' will have its own baby without the male partner. It is not new, we have done it since we first domesticated animals.

It's the basis for Eugenics. Selective breeding. We even do it with plants. Corn is the result of centuries of it. The original plant looked like grass, somewhat.

I'm fairly certain that "cloning" whiptails exist quite naturally in the wild. So it isn't like these scientists discovered anything unknown. "But the New Mexico Whiptail, as well as several other all-female species of whiptail lizard, does reproduce, and all of its offspring are female. Moreover, it reproduces by parthenogenesis -- its eggs require no fertilization, and its offspring are exact and complete genetic duplicates of the mother. " American Museum of Natural History
